TILLER-QUADRANT.

ostess.

To all whom it may concern:

Be it known that we, CLARENCE W. PIIALEN and FREDnnIoK E. GIDDINGS, a citizen of the United States of America and a subject of the King of Great Britain, respectively, and residents of the city of Ottawa, Province of Ontario, Canada, have invented certain new and useful Improvements in Tiller-Quadrants, of which the following is a specification.

The invention relates to improvements in tiller quadrants, as described in the present specification, and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel arrangement and construction of parts, whereby the quadrant carries an adjustable tension member operatively connected to the tiller ropes.

The objects of the invention are to devise a tiller quadrant of simple and durable construction, which may be readily clamped upon a rudder post, and which may be easily operated to take up the slack or release the tension of the tiller ropes connected thereto, thereby eliminating the necessity of turn-buckles or other connections intermediate of the length of the tiller ropes as ordinarily found necessary for this purpose.

In the drawings, Figure 1 is a plan view of the invention. Fig. 2 is a sectional view on the line A B in Fig. 1.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the quadrant having the side arms 2 and 3, and the center arm 4 extending outwardly to the arc-shaped face 5. The arc-shaped face 5 of the quadrant has the flared lips 6, and the peripheral grooves 7 to receive the tiller rope.

8 is a head formed in the center of the quadrant, said head having the orifice 9 therethrough, and the half sect-ion 10 split away to form a clamp, said section 10 being held to the head proper by the bolts 11, whereby the quadrant may be firmly clamped upon the upper end of a rudder post, when the said post is lnserted through the orifice 9.

The quadrant 1 is recessed at 12 on the under side thereof, leaving the bridge-piece 40 extending across said recess on the upper side.

Specification of Letters Patent.

Application filed April 17, 1913.

Patented Feb. 1'7, 1914.

Serial No. 761,662.

13 is a drum fitting in the recess 12, and having the peripheral grooves l-t cor1'c sponding to and in alinement with the quadrant grooves 7.

15 is a ratchet formed around the drum 13 above the grooves 14.

The drum 13 has a stud 16 projecting upwardly therefrom, and through a central orifice in the recess in the bridge-piece 40, said stud terminating in the squared end 17.

18 is a stud projecting downwardly from the drum 13.

19 is a strap plate bridging the recess 12 beneath the drum 13, and having the orifice 20 through which the stud 18 of the drum extends. The strap plate 19 is secured to the quadrant by the bolts 21.

22 is a pawl pivotally mounted on the upper side of the arm 4 by the screw 23, and having the tooth 24: thereof turned inwardly, and engaging with the teeth of the ratchet 15.

In connecting up the quadrant, it is clamped as hereinbefore explained upon the upper end of a rudder-post, and the ends of the tiller rope connected thereto in the following manner: The end 26 is passed around one of the grooves 7 from the arm 2 to the arm 3, and around the rounded end of the quadrant are at the arm 3, and into the corresponding groove on the drum 13, where it is secured in any desired manner, such as by looping the same around a pin, or passing the same through a hole or holes in the groove, and knotting or otherwise tying it. The end 25 of the rope is brought around the other groove 7 of the quadrant are from the arm 3 to the arm 2, and around the rounded end of the are to the corresponding groove 14 on the drum 13, where it is secured in a similar manner to the rope 26, and at a point diametrically opposite.

It will now be readily understood that the drum may be turned with an ordinary wrench fitted upon the squared upper end, and when said drum is turned in the direction of the arrow, it will coincidently wind both ends of the tiller rope therearound, the pawl 22 engaging with the teeth of the ratchet 15, and holding the drum to any degree of tension to which it may be turned. In like manner the pawl may at any time be released from engagement with the teeth of the ratchet, and permit the drum to unwind the ends of the tiller rope therefrom and slacken the same, thus making it possible to use rope of an ordinary quality, as the difference in length due to climatic changes can quickly be accounted for by the turning of the drum on the quadrant. Furthermore, the necessity for having the rope looped or provided with turn-buckle devices intermediate of its length is obviated, and the sides of the rope, that is, each length between steering wheel and tiller quadrant kept exactly at equal length at all times, thereby keeping the set or position of the steering wheel constant. That is, if the steering wheel is fastened to the tiller rope on a center, it is not turned to one side through the necessity of taking up slack on only one side of the tiller rope, as is customary.

It must be understood that many modifi cations may be made in the arrangement of the several parts of the invention without departing from the spirit of the same, that is, the drum may be mounted in various ways or may be replaced by a reel or other device, and we do not wish to be confined to the exact construction as shown in the accompanying drawings.

lVhat we claim as our invention is:

l. A tiller quadrant comprising a frame and a reel mounted in said frame and to which the ends of the tiller rope are secured.

2. A tiller quadrant comprising a frame having an arc-shaped rope face and a reel centrally arranged thereon and adapted to receive the rope ends from said rope face.

3. A tiller quadrant or the like comprising a split clamp, one section of said clamp having quadrant arms extending therefrom and supporting an outer arc-shaped rope face, a winding drum having a ratchet face and rotatably mounted centrally in the quadrant frame and a pawl pivotally mounted on said quadrant frame and engaging with the ratchet face of said Winding drum.

4. A tiller quadrant comprising a quadrant frame having a. recessed center portion centrally bridged and radial arms supporting an arc-shaped outer flange, a winding drum located in said recess and having a stud extending upwardly therefrom through the bridge over said recess and terminating in a squared end and a stud extending downwardly therefrom and a ratchet face, a strap plate secured across the under side of said recess and having an orifice and a ratchet pawl piv tally mounted on said quadrant frame and engaging with the ratchet face of said winding drum.

Signed at the city of Ottawa, Province of Ontario, Canada, this seventeenth day of March, 1913.
